ImmunoCAP Tests Setting the Standard in Allergy Diagnostics

Putting the patient first

Our mission is to provide clinically relevant and clinically accurate tests and services to enable clinicians to improve the diagnosis and management of patients with allergic disease and asthma. ImmunoCAP™ tests can be run on reliable and automated Phadia™ Laboratory Systems, which feature scalable instrument solutions for different throughput needs.

Gold standard testing technology you can trust

As pioneers in allergy diagnostics we have more than 50 years of experience in allergen production and specific IgE product development Our products are documented in more than 6,000 publications2 and referenced in multiple health guidelines. These may be some of the reasons for ImmunoCAP being acknowledged as the gold standard technology1 for specific IgE blood testing.

Designed to Offer High Performance and Reliable Results

ImmunoCAP blood tests are sandwich tests, which means that the solid phase ensures binding of all relevant antibodies. This is achieved through an optimized amount of cellulose material with a very large surface area providing a uniquely high binding capacity in each ImmunoCAP test.

In addition, ImmunoCAP tests offer your laboratory the ability to provide clinicians with fully quantitative measurement and reproducibility. This benefit is possible because our tests are linear and have low limits of quantification.

Dedicated to research and development

We are shaping the future of allergy diagnostics and management, continuously delivering new, innovative products and new science to meet clinical unmet needs. Over the last decade, we have introduced or significantly updated more than 40 products, primarily in the field of allergen component testing. We are engaged in several collaboration projects with the scientific community, including our current involvement in more than 100 ongoing trials with more than 50,000 patients worldwide.3

The ImmunoCAP test menu: Sophisticated solutions for broad diagnostic needs

The ImmunoCAP test menu includes sIgE, sIgG, and sIgG4, and biomarkers for eosinophilic inflammation and mast cell activation. All available on the same reliable automated Phadia instruments. Our specific IgE test menu covers a broad range of more than 550 allergens with allergen mixes, whole allergens, and more than 100 allergen components. Specific IgE tests are provided as single tests, multiplex, and even point-of-care tests.



“To date the most commonly used system to determine allergen-specific IgE is the ImmunoCAP system considered as the ‘gold standard’ for the in vitro diagnosis of allergic conditions.”
